Good Day,
We are searching for a voltage reference for a ruggedized data acquisition system. The reference in each device will be characterized over temperature, so absolute accuracy and temperature drift aren't the primary concerns. We can calculate those out. We are looking for the best device in terms of long-term drift and thermal hysteresis. A heated reference is not a good option, as our temperature profile is too wide. These devices will be operated from -55 to 125C.
The output voltage isn't critical either - we can work with anything from 1.25V to 5V.
Obviously, something in the LS8 package or a thru-hole hermetic package is likely.
What reference would Analog suggest for this application? LT6654 or LT6656 both seem like good choices, but perhaps there's something better?
Thank You,
Ben
